Recent high-profile bridge collapses have brought attention to the need for a major infrastructure overhaul in many countries, but the global economic downturn means far less money is available even for routine maintenance, let alone far more costly repair and rebuilding. Furthermore, the long times typically associated with bridge repair or replacement, and the resultant cost and inconvenience that partially or fully closed bridges pose to both commuters and commercial haulers gives public officials cause for concern. Not surprising, therefore, many commercial, educational, and government organizations are working to develop what can loosely be called "rapid bridge replacement" technologies.
